Hi all,

Thank you Nihar and Barbara for your nice comments. Please find the new version for my abstract with your comments implemented here:

TP_HP_abstract_v7.pdf

Thanks,

Tanmay

Hello Tanmay,

Thank you for your reply and modifying your abstract.
I would request you to be present at this week's HP-pwg meeting to
discuss on your abstract.

Please find my comments below on your updated abstract.

L6-7: "Jets formed from hard parton scatterings early in heavy-ion
collisions traverse …" ->
"Jets—produced from hard scatterings of partons early in heavy-ion
collisions—traverse through…"

L16: "…which are expected to spend more time in the QGP medium. " Not
sure that is true at RHIC. Please rephrase this.

L18: "…observable from 200 GeV pp and Au-Au collisions collected by the
STAR experiment. " -> "…observable in p+p and Au+Au collisions at $\sqrt
s_{\rm NN}$ collected by the STAR experiment. "

L19: "We also show fully corrected Girth, … from 200 GeV pp collisions…"
-> "We also show fully corrected other jet shape observables like Girth,
… in p+p collisions." Then make a new sentence.
"The exploratory studies of these observables in Au+Au collisions are
discussed."
(Do not need to mention 200 GeV here as you have mentioned it above
once)

Cheers
Nihar
